On Tuesday, audited financial documents revealed that OpenAI's total spending for 2025 amounted to $34 billion, with a net loss of approximately $38.5 billion. This figure represents a nearly eightfold increase compared to the $5.1 billion loss recorded in 2024, raising questions about the financial sustainability of the world's most highly valued artificial intelligence company.
The data shows that OpenAI generated roughly $13 billion in revenue for 2025, but its expenditures vastly exceeded this income. Research and development costs alone reached $19.2 billion, while sales and marketing expenses were close to $5.8 billion. Concurrently, OpenAI confidentially submitted IPO registration documents to the U.S. Securities and Exchange Commission earlier this month, with some executives and investors anticipating a public listing as soon as this autumn.
Understanding the Significant Loss
It is important to note that, according to sources, the vast majority of the $38.5 billion net loss stemmed from a non-cash accounting charge related to the company's prior equity restructuring. This specific expense is not expected to recur. Excluding this charge, along with other non-cash items such as stock-based compensation and credits for Microsoft (NASDAQ: MSFT) computing resources, OpenAI's actual operating loss was approximately $8 billion.
The composition of the $38.5 billion net loss must be understood in the context of OpenAI's corporate transformation. In 2025, the company completed its transition from a non-profit entity to a public benefit corporation. Prior to this, investors held convertible interests rather than traditional equity. Under U.S. accounting standards, these interests were treated as liabilities and were periodically revalued as the company's valuation increased.
Sources indicate that as OpenAI's valuation continued to climb, the fair value changes of these investor interests generated a paper charge of around $30 billion. The financial documents show total losses related to the fair value changes of convertible interests and warrant liabilities amounted to approximately $41.5 billion.
After accounting for other factors like interest income and expenses, OpenAI's total net loss for 2025 reached $60.4 billion. This figure was later reduced to the reported $38.5 billion by allocating about $17.9 billion to "net loss attributable to noncontrolling members' interests" and around $4 billion to "net loss attributable to redeemable noncontrolling interests." Sources state these structural charges are not expected to reappear following the completion of the transformation.
Rapidly Expanding Operational Costs
Even after stripping out non-cash items, OpenAI's operational losses are substantial. Financial documents indicate an operating loss of $20.9 billion for 2025, compared to $8.8 billion in 2024.
On the expenditure side, R&D costs surged from $7.8 billion in 2024 to $19.2 billion. Sales and marketing expenses grew from $1.1 billion to $5.7 billion, while the cost of revenue expanded from $2.7 billion to $7.5 billion.
Microsoft constitutes OpenAI's largest single cost source. The financials show that OpenAI paid Microsoft a total of approximately $17.2 billion in 2025. This included $10.6 billion for R&D (primarily considered model training costs), about $6 billion for cost of revenue, $527 million for sales and marketing, and $42 million for general and administrative expenses. In turn, Microsoft paid OpenAI $303 million, and SoftBank paid $867 million.
As of the end of 2025, OpenAI's total assets slightly exceeded $50 billion, with nearly half being cash. The company completed a $122 billion funding round earlier this year, at which point its valuation (excluding the new investment) had reached $730 billion.
IPO Window Approaches Amidst High Growth but Unclear Profitability
Despite the massive loss, OpenAI's revenue growth remains exceptional. Full-year 2025 revenue of about $13 billion represents a more than 2.5-fold increase from the $3.7 billion recorded in 2024. By the end of 2025, the company's monthly revenue had reached $2 billion, whereas its quarterly revenue at the end of 2024 was only about $1 billion.
However, this rapid revenue growth has not been sufficient to cover the continuously expanding cost curve. Total expenditures for 2025 hit $34 billion, which is over 2.6 times the revenue for the same period, highlighting a significant gap between scaling operations and achieving profitability.
Against this backdrop, OpenAI is accelerating its IPO process. Having already confidentially filed with the SEC, CEO Sam Altman has characterized this move as keeping the option of entering public markets open, while also suggesting that remaining private remains a viable path. Some executives and investors expect a listing as early as this autumn, which would place it in direct competition with Anthropic, which also filed for an IPO this month with a valuation of $900 billion.
